Outputting to console, but on the same line as the last output in PowerShell

Question

I'm writing a script to backup our SVN repositories, based on http://www.codeproject.com/KB/powershell/SVNBackupPower.aspx. It works sweet, but when it's waiting for the ZIP to complete, I'd like it to issue a dot instead of a new line each iteration. So,

Waiting for ZIP ...................

as opposed to

Waiting for ZIP
Waiting for ZIP
Waiting for ZIP
Waiting for ZIP
(you get the picture)

I guess the equivalent in BASIC from back in the day would be:

PRINT ".";

But what's the PowerShell equivalent?

Answer 1

Pretty simple...

write-host "Waiting for zip" -nonewline
while ($inloop -eq true) {
    write-host "." -nonewline
    $inloop=Get-LoopStatus($Thingy)
}
write-host "."

The key is -nonewline. You can even make those additional bits different colors via -foregroundcolor.

Answer 2

You could also use the write-progress cmdlet to visualize a progress bar.
